If you're using [acts-as-taggable-on](https://github.com/mbleigh/acts-as-taggable-on) on some of your models, you may find an error like this when trying to manage them from ActiveAdmin:

    undefined method `tag_ids_contains' for #<MetaSearch::Searches::Post:0x007faa3d680b70>

To fix this, refer to the [[Preventing Extra Queries on Index Pages]] page to specify the attributes where you want MetaSearch on. Like this:

    ActiveAdmin.register Post do
      filter :title
      filter :body
    end
